1 Claim.

The present invention relates to new and useful improvements in agricultural implements in general and particularly to hydraulic disk frames for use in conjunction with the Ferguson linkage system on Ford tractors.

An important object of the present invention is to provide a frame of the aforementioned character comprising anovel construction and arrangement whereby the disks may be operated at such an angle as to have a continuous suction in the soil, also to scour better in different kinds of soil and, still further to turn said soil over in a manner substantially similar to a disk plow. An-

' other very important object of the invention is to provide a hydraulic disk frame of the character described which, with the disk gangs thereon may be lifted clear of the ground and transported on the tractor through the medium of the linkage system.

Still another very important object of the invention is to provide a hydraulic disk frame of the character set forth which, as a result of the manner in which it is connected to the Ferguson linkage system, may be conveniently adjusted horizontally and vertically.

A still further important object of the invention is to provide a hydraulic disk frame of the character described comprising resilient means of a novel construction for holding the inner ends of the disk gangs at the desired depth, whereby flexibility of said disk gangs will be had.

Other objects of the invention are to provide a hydraulic'disk frame which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact, light in weight, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts through the several views, and wherein Figure 1 is a top plan view of a hydraulic disk frame constructed in accordance with the present invention, showing the device connected to a tractor.

Figure 2 is a view in side elevation thereof.

Figure 3 is a view in front elevation showing the compression and tension links of the Ferguson system in cross-section.

Figure 4 is a view in vertical longitudinal section through an intermediate portion of the device. r

Figure 5 is a cross-sectional view through an intermediate portion of the device taken substantially on the line 5-5 of Figure 4.

Referring now to the drawings in detail, it W111 be seen that the embodiment of the invention which has been illustrated comprises a transversely elongated, welded frame of suitable metal, which is designated generally by reference numeral I. The frame I includes a front bar 2, a relatively elevated rear bar 3 and angular side bars 4 extending between the end portions of said bars 2 and 3.

Drawbars 5 are ment in a horizontal plane. Gangs 6 of rearwardly converging disks are connected, at intermediate points, to the outer drawbars 5. Drawbars I are connected to the inner ends of the disk gangs 6. Bumpers 8 are ner ends of the disk gangs 6.

A Ferguson linkage system on the rear end of a "Ford tractor 9 is indicated at H]. The system l0 includes the usual tension links H which are connected to the bar 2 of the frame I, and a compression link link I2 is connected to a verging bars l3 which frame I.

An angular beam I4 is suspended, at an intermediate point, from the upper portions of the bars [3 by members IS. The rear end of the beam I4 is secured to the bar 3. The forward portion of the beam l4 extends downwardly and'the forward encl portions of the drawbars 1 are pivotally connected thereto at It.

pair of upwardly conrise from the bar 2 of/the Depending from thebar 2 at an intermediate point is a vertically slotted guide H. A brace I8 extends between the lower portion of the guide l1 and the forward end portion of the beam M. A substantially L-shaped, vertically slidable rod I8 has its lower end portion operable in the guide l1. Slidably mounted on the lower portion of the rod l8 isan angular bracket I 9, said bracket including a bifurcated vertical leg 20 which straddles the horizontal lower end portion of said rod 3. Mounted transversely on the horizontal lower portion of the rod l8,-between the vertical leg 20 of the bracket of said rod I8, is a bar lugs 22 therein which bars I. v

I The upperend portion of the rod l8 exte shdably through the beam l4. Slidably moun t i on the upper portion of the rod l8, below the beam H, isa crosshead 23. A-pair of J-bolts 24 I9 and the vertical portion 2| having elongated openaccommodate the drawjournaled on the front of the frame I at the ends thereof, for swinging moveprovided on the inl2. The compression I 2 V I V v adjustably anchor the crosshead 23 to apertured ears 2! which project rearwardly from the bar 2. A coil spring 26 is mounted under compression on the rod ll between the crosshead '23 and the bracket 19. Braces 21 extend from the bar Ito the front portion of the beam l4.

The construction and arrangement is such as to permit. maximum flexibility and adjust ability of the gang disks 8. The drawbars I, which carry the inner ends of the rearwardly converging gang. disks 8, are yieldingly urged downwardly by thecoil spring 26. The tension of this coil spring 28 may be conveniently adjusted or regulated as desired through the medium of the J-bolts 24. Thelinkage system In is adapted to readily lift the entire structure,

It is believed that the many advantages of a hydraulic disk frame constructed in accordance with the present invention will be readily understood and although apreferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

- What is claimed is:

An agricultural device of the character described comprising' a transversely elongated frame including a front bar connected to the tension links cf a system of implement control,

of. the type including a. compression link, on a I with the gang disks 6 thereon, clear of the ground to be transported on the tractor 9.

tractor, means connecting said front bar to the compression link of the system, a beam mounted longitudinally on the frame and including a downturned forward end portion, a pair of drawbars loosely connected to the forward end portion of said beam for lateral and vertical swingin movement, a pair of drawbars journaled on the end portions of the frame for swinging movement in a horizontal plane, said drawbars for connection with rearwardly converging gangs of disks, means for yieldingly urging the first-named drawbars downwardly, and means for limiting the lateral swinging movement of said firstnamed drawbars.
